摘要
河北某植物蛋白公司生产污水处理项目,采用酵母菌反应池-UASB-SBR-MBR的工艺流程,设计处理量50 m^3/d,工程系统运行稳定可靠,出水达到既定要求。但工程建设初期未安装自动化系统,人工操作较为繁琐,预警报警机制不完善,人工巡查工作量大。此次自动化系统工程在现有工艺设备基础上,利用物联网技术及无线DTU模块搭建自动化控制系统网络,免去大量线缆桥架铺设工作。根据污水处理工艺,设计PLC程序,完成特定的控制功能,利用WINCC组态界面实现人机交互,构建了1套完整高效的自动化控制系统。
The microzyme-UASB-SBR-MBR process had been applied to the wastewater treatment project by a vegetable protein company in Hebei Province,China.Its treatment capacity is 50 m^3/d,its working system runs stably and reliably,and its effluent meets the fixed requirements.However,since no automatic system was established at the initial stage of the project,the manual operation was rather complicated,the forecast and alarm mechanisms were imperfect,and the manual inspection loads were heavy.This time,based on the existing technical equipment,the present automatic control system has applied the internet of things technology and DTU wireless module to the setting up of an automatic control system network,so as to avoid the heavy work of cable laying and bridges mounting.Based on wastewater treatment technologies,a complete set of highly efficient automatic system has been established,by means of designing the PLC program,achieving specified control functions,and realizing man-machine interactive control with WINCC configuration interface.
